Review on 🔊 HiLetgo 3pcs M28 Wireless Bluetooth MP3 Audio Receiver Board BLT 4.2 - Lossless Decoder & Stereo Sound Module with Bluetooth 4.2 Connectivity by Joel Payne

First of all, they are incredibly cheap, so you should be skeptical when buying them. I bought them about 6 months ago. I'm mostly happy with them, but they have some weird quirks that annoy. 1) They MUST be turned off when not actively in use or they will go into a weird frozen state where they won't work until the power is turned off. 2) One in three died within a month. not that big of a problem because they're so cheap, but it's something to be aware of. 3) In the Bluetooth menu they are all named the same and I can't change that which makes pairing with different ones a little tedious. Mostly good, but not perfect. You pay a low price for weird quirks.
